Hello! I'm having the same problem on my mr6400 v4, do you have a fix for this? I'm currently using the modem with modem manager provided in this image:
Hi @fachos first of all thanks for the effort, this image worked right away and survived reboot, promoting to most stable image I tried so far on the v4. I have noticed that it is based on 21.02.0. Since than the 21.02.1 is out and I am wondering, long term how can I upgrade without destroying the changes you made in order for this internal modem to work? I have never compiled an image myself but if you have a good reference it would give it a try. Thanks.
May I know what the changes are from the one in your repo vs the official build? What's the issue that's preventing the official build from working?
Secondly, does anyone have issues with accessing the interface of the LTE modem? It's supposed to be accessible via 192.168.0.1, but doesn't seem to be working on the v4.
Hi
The main difference is that I use APN profiles to start the session. My version make sure that the default APN profile is configured correct before the modem attach the network.
If the default profile is wrong I will set the modem to Airplane mode on and change the profile and then set Airplane mode to off. Not all cellular operator accept an "empty" APN profile when the modem attach to the network.
Thank you for clarifying. May I know how do I access the LTE modem GUI interface? Been reading on the forum that some people were able to access this via 192.168.0.1, but this doesn't seem to be working on mine.
As far as I know most LTE modems are accessed via cli, with AT-command, QMI or MBIM. It´s not that common to use GUI.
My modem, in the MR200v4, has no GUI.
Hello there, I've been looking at commits for the TP-Link MR series routers (i.e. those with 4G modems) and keep seeing DTR. I tried looking this up, and seems like it means Digital Trunk Radio. The MR6400 lists a DTR Quirk Patch file in one of the commits for adding OpenWrt support. May I know the signficance of this file?
